Abstract
Se describe un proceso para recuperar fosfato de litio y sulfato de litio de un silicato que contiene litio. El proceso incluye agregar de 800 kg/t a 1600 kg/t de ácido sulfúrico a una suspensión del silicato que contiene litio y de 40 kg/t a 600 kg/t de una fuente de fluoruro para producir una mezcla de lixiviación y calentar dicha mezcla de lixiviación. A continuación, se separa una solución que contiene litio de la mezcla de lixiviación y se aumenta su pH secuencialmente a un pH 3,5 a 4, un pH 5,5 a 6 y luego un pH 10,5 a 11 para precipitar, respectivamente, un primer, segundo y tercer conjunto de impurezas de la misma. El primer, segundo y tercer grupo de impurezas son separados de la solución que contiene litio y se agrega cal para mantener una concentración de Ca soluble de por lo menos 30 mg/L. Luego se ablanda la solución que contiene litio agregando dos cantidades secuenciales de fosfato para precipitar la fluorapatita y la apatita, respectivamente. Se agrega una tercera cantidad de fosfato para producir un precipitado de fosfato de litio que posteriormente es separado. El precipitado de fosfato de litio separado es digerido luego en ácido sulfúrico para producir una mezcla de digestión de la que se separa un precipitado de sulfato de litio. Se agrega un hidróxido de metal alcalino a la solución separada para producir una solución de fosfato de metal alcalino y esta se recicla para su uso como fosfato en el proceso.
